Can strict-liability statutes constitutionally apply to juveniles in Utah? In re T.S. Explained

The Utah Court of Appeals in In re T.S. addressed whether strict-liability criminal statutes violate constitutional due process when applied to juveniles. The case arose when a fifteen-year-old was charged with rape of a child after consensual sexual intercourse with a twelve-year-old classmate.

Background and Facts

T.S., aged fifteen, and A.R., aged twelve, attended the same school and began dating. After A.R. invited herself to T.S.’s home, they engaged in consensual sexual intercourse. A.R. had previously told T.S. she had sexual experience. When A.R.’s father discovered the encounter through her diary, he reported it to police. The State filed a delinquency petition under Utah Code section 76-5-402.1, a strict-liability offense for rape of a child.

Key Legal Issues

T.S. challenged the statute on two grounds. First, he argued that applying strict-liability crimes to juveniles violates due process fundamental fairness because adolescent brain development prevents juveniles from having constructive knowledge their actions might be criminal. Second, he contended that applying the statute to his case would produce an absurd result under In re Z.C., which protected juveniles in situations where no clear victim or perpetrator could be identified.

Court’s Analysis and Holding

The court rejected both arguments, reviewing the constitutional challenge for correctness. While acknowledging that juvenile brain development affects decision-making, the court distinguished cases limiting harsh sentences from the legislature’s power to define criminal conduct. The court emphasized that proof of a culpable mental state is not a due process requirement, and ignorance of the law cannot serve as a defense for juveniles. Regarding In re Z.C., the court found the juvenile court properly distinguished this case by identifying T.S. as the perpetrator and A.R. as the victim, unlike the mutual culpability in Z.C.

Practice Implications

This decision clarifies that strict-liability statutes remain constitutional when applied to juveniles, despite advances in understanding adolescent brain development. Practitioners defending juveniles should focus on factual distinctions from precedent cases and available statutory diversions rather than broad constitutional challenges. The court’s analysis suggests that while juveniles may receive different treatment in sentencing and procedural contexts, they remain subject to the same substantive criminal prohibitions as adults.
